Abstract: PURPOSE:To simply form a drive voltage generation circuit for driving a voltage-controlled type radiation controlling switching element, such as an insulated gate type bipolar transistor or the like, without taking any special measure, by adjusting the secondary side coil output voltage of a transformer installed in an electric discharge loop for putting the adjusted output voltage to use. CONSTITUTION:A secondary switching element Q1 which controls the radiating operation of a flash discharge tube Xe is formed out of a voltage controlled type element, for example, an insulated gate type bipolar transistor. Drive voltage being impressed on the pressure terminal of the switching element Q1 is generated via a simple control voltage generation circuit Co. The secondary voltage of a transformer T1 in the electric discharge loop of a capacitor C2 causing electric discharge when a first switching element SCR which applies an electric current to a main capacitor C1 which stores radiating electric charges by a low-voltage power supply (Bat) is turned on, is adjusted to a specific value by the control voltage generation circuit CC, so that the adjusted secondary voltage is impressed on the voltage terminal of the switching clement Q1.

Title: Load drive circuit and ic regulator using n-channel power mosfet
Inventor: SUGAYA ATSUSHI
IPC: H02M3/155
Filed: 1988-12-10
Abstract: PURPOSE:To keep stable switching and stable high speed chopper control even in the case of a load whose resistance changed considerably by making a power NMOSFET conductive and nonconductive not through a load. CONSTITUTION:An electric charge is supplied (charged) to a stray capacitor 24 in existence between a gate and a source of a power NMOSFET 11 not through a load 51. Thus, an event of an increase in a source level due to the existence of the load 51 is not caused and a gate voltage is not boosted over the voltage of a power supply 61, then the applied voltage between the gate and the source is ensured to make the drain and source of the power NMOSFET 11 conductive. Thus, even in a remarkable change in a load resistance or independently of the load resistor size, smooth and stable switching operation (load drive control) and high speed chopper control of the power NMOSFET are always attained.

Title: Catalyst temperature controller for internal combustion engine
Inventor: MITSUYASU MASAKI
IPC: F02B23/10
Filed: 1990-11-20
Abstract: PURPOSE:To enable repidly increasing the catalyst temperature by causing a first air-cylinder group to be kept inoperative to cause only a second air- cylinder group to operate, and thereby causing an increased amount of fuel to be supplied to the second air-cylinder group. CONSTITUTION:An air cylinder arrangement is divided into a first air-cylinder group and a second air-cylinder group, and a suction air cut-off valve 8 is disposed in each of suction branch pipes 2 of the first air-cylinder group. Within an exhaust passage are disposed a tertiary catalyst converter 12 and a temperature sensor 13 for detecting the temperature which represents the temperature of the catalyst converter 12. An electronic control unit 20, when the temperature detected by the temperature sensor 13 is lower than that set beforehand, closes all the suction air cut-off valves 8 to stop supply of fuel to the first air-cylinder group and simultaneously supplies an increased amount of fuel to the second air-cylinder group so as to obtain an engine output torque substantially equal to that during an all-air-cylinder operation. By this, the temperature of the catalyst converter 12 can be rapidly increased when the catalyst temperature is low.

Title: Suction device of engine
Inventor: MATSUMOTO HIROMITSU
IPC: F02B31/00
Filed: 1989-11-30
Abstract: PURPOSE:To carry out a smooth operation and reduce the exhoust of uncombusted hydrocarbons by furnishing an aux. throttle valve shutting only at the time of low load in a position of a suction passage downstream a throttle valve, putting a vent situated eccentric from the combustion chamber in communication with point between the valves and in the neighborhood of a suction hole, and accomplishing good performance of combustion under a low load operation. CONSTITUTION:Because the degree of opening of the primary throttle valve 1c is less immediately after starting of an engine or under low load operation, the neg, pressure in a suction passage 15 is high, and accordingly a pressure chamber 17a is sucked and an operation rod 17d is pulled up. Therefore, an aux, throttle valve 16 is turned and the suction passage 15 is blocked or put in low degree opening. When this aux. throttle valve 16 is shut, the mixture gas supplied from a carburettor 1 passes through communication paths 24, 25 and a draft pipe 22 and is inhaled into the combustion chamber 9 from a draft hole 21. This communication path or draft hole 21 is thinner relatively than the suction passage 15, and the draft hole 21 is oriented toward the combustion chamber 9 and opens in a potion eccentric from the center of the combustion chamber, so that the mixture gas supplied therefrom becomes a high speed jet stream and is inhaled into the combustion chamber 9 so as to generate there swirls.

IPC: H05K7/00
Filed: 1988-12-13
Abstract: PURPOSE:To improve operatability by dividing a hard grommet into a plurality of pieces, and engaging a guide projection with a guide hole. CONSTITUTION:A hard grommet 10 is divided into a plurality of pieces 10a. A guide projection 16 is formed at one end of the divided piece 10a, while a guide hole 17 with which the projection 16 is slidably engaged is formed at the other end thereof. The projection 16 is engaged with a guide groove 17a. Therefore, if the respective pieces 10a are separated enough to enable a wire harness or the like to be inserted, the projection 16 isn't pulled out of the hole 17. The separation with the hard grommet inserted into a soft grommet enables preferable operatability.

Abstract: PURPOSE:To aim at improvement in efficiency over the full load of a hydraulic turbine and prevention against vibration and noise at the time of partial load operation by installing plural numbers of fine holes, spraying a high pressure fluid, on at least a lower end face in both upper and lower end faces a guide vane blade. CONSTITUTION:A lot of fine holes 12 are installed on both upper and lower end faces of a blade 11b in the flowing direction of pressure water. Each of these fine holes 12 is connected to a conduit 13 consisting of each blade hole 13a installed in the blade 11b and a spindle hole 13b installed in a spindle 11a and drawn out to a shaft end, while a high pressure fluid is fed to this conduit 13 via a connecting pipe 14. When this high pressure fluid is sprayed toward both upper and lower fixed walls from each fine hole 12, a jet 15 prevents a leaking flow from the high pressure side P.S. of a guide vane 11 to the low pressure side S.S. and thus any turbulence of a flow to the suction pressure side of the guide vane 11 is prevented from occurring.
